Abstract

This pressurized-gas storage assembly includes a pressure vessel having a gas storage chamber and access opening, a polar boss extending through the access opening, a plastic liner lining the gas storage chamber, and a fitting body. The plastic liner includes a nipple portion that extends into the polar boss, terminates at an annular rim, and has a screw-threaded radially inner surface region. The fitting body includes a head portion, an extension longitudinally extending from an end of the head portion and having a screw-threaded radially outer surface region, and an annular shoulder. The annular shoulder has an annular recess formed therein, with a compressible O-ring being accommodated within he annular recess. By inserting the extension through the access opening and positioning the screw-threaded radially outer surface region of the extension into mechanical engagement with the screw-threaded radially inner surface region of the nipple portion, the O-ring is compressed between the annular shoulder of the fitting body and the annular rim of the liner. As a consequence, the O-ring is compressed and a hermetic seal is established between the inner liner and the fitting body, thereby preventing escape of stored compressed gas through the access opening.

Description

The closed component of belt material storage tank and the Motor Vehicle of this assembly is housed
1. FIELD OF THE INVENTION
The present invention relates to have the storage tank of liner, particularly have the storage tank of plastic gasket, be used to store superheated steam fuel.
2. the explanation of prior art
Pressurized container is widely used in the liquids and gases under the storage pressure.An ever-increasing application of pressurized container is that they are used to store alternative fuel, and such as rock gas or propane, these alternative fuel are used for Motor Vehicle, in automobile.Think that day by day as fuel for motor vehicle, rock gas and propane are more more desirable than gasoline.Therefore, designed various measures,,, thereby the Fuel Petroleum Motor Vehicle has been transformed into gas fuel or propane fuel Motor Vehicle so that use rock gas or propane substituting gasoline by repacking Fuel Petroleum Motor Vehicle.In addition, the Motor Vehicle of producing at present is designed to use rock gas or the propane source of acting as a fuel is moved.
The container that is used for storing natural gas and propane preferably is equipped with plastic gasket, and the gas that it is used to keep being stored can not leak.The whole inner surface of the best covering pressure container of plastic gasket comprises the neck part, and neck partly limits the inlet opening that the fuel of packing into is used.For preventing that fuel from leaking in the inlet opening, can use O shape circle or other seal arrangement.
